chargers; and Ido hereby declare the following to be a full, clear, and exact descrip! tion of the mvention, such as will enable others skilled in the art to which itappertains to make and use` the same.

My invention relates to improvements in devices for the discharge of solid residue from Vcontinuously working, water'sealed distillingi-furnaces and the object of my invention is to provide a discharger o the class referred to, permitting the delivery of the `said residue withoutbeing immersed in and passed through the water.

I attain my object by the constructionv and combination of parts, as herein set forth va'nd described and as illustrated on the drawing herewithwhichishows a vertical "section of my improved device.

In `distilling processes a seal is generally `required for the complete exclusion of air and such' a seal is particularly indispenable in continuously working distilling devices.

One way of electively preventing access of air into the distilling compartment durthe continuous discharge of the residue of the distilling process is the employment of a water-seal which is in many cases provided by immersing the bottom of a furnace shaft in water and removing the material by means o'f aninclined" screw couveyer, ele

, urated during its discharge. They-therefore vator or similar device.

These known contrivances have the great disadvantage that the material be'c'omes sat- `40 permit of employment only in those-cases where even a considerable amountof water in the distilled residue 1s not detrimental,

while they are useless wherever the chemical or physical nature of the product of d1stillation is such that the product would be harmed lby wetting.

' On the other hand it has been proposed to employdrums or cylinders having boxes or buckets for the continuous discharge of the 4lor'esidue. The knowndevices of this class are, however2 incapable of preventing the entrance of air into'the furnace; on the contrary, they cause the air 'present in the boxes 0r buckets to be forcibly driven into the distilling compartment by the very material they receive.

Specication of Letters Patent.

All of these several'disdvantages are ob# d l viated by my inventionymy improvements permittmg the continuous and gentle discharge ofthe material withoutV flooding it with water and without permitting any air to get into the distilling compartment..

To the bottom 1 cfa distilllng furnace am' suitable' contrivance may be attached whic` continuously delivers the material coming from the furnace. In the example shown in the drawing it comprises an ordinaryr rota-l table scraper table-2 which is closed olf air tight against the outside by a jacket 3. The material being put in Vrotary motion by lthe said scraper table 2 will beremoved" by a shovel-like scraper blade 4 from the table and throughthe closed chute 5 be :lied into the delivery device. This device comprises a drum o r cylinder 7, Vprovided with buckets or boxes 6, said drum rotating in a casing composed of segmental portions 8, 9, 10. These segmental portions are larger than the openings of the buckets, so that the latter during the rotation of the drum or cylinder' are amply covered. Preferably the upper segmental portions 8 and 9 may be shaped to form a socket 11 for vconnection with the chute 5.

The bottom segmental piece 10 may be attached to andY in the drawing appears integral with the water-tank 12 in which about onehalf of the drum 7 is'immersed. Also the segmental piece 9 is partly immersed in the water. The outer faces ofthe buckets 6 make a sliding fit with the inner face of Vthe casing 8.-9--10, andthe buckets extend the entire length of the casing, so that no water can' escape from the tank 12 through the spout 16'.

loc

This segmental piece is connected by .a

. is shown as being entirely filled with water,

tation of, t; 'h`e bucketwheel the water commences giwin out -of the bucket, because 4now the distil ing gases from the furnace are permitted to enter through the pipe 13.v

The bucket filled with the distilling gases then receives the material gliding down the chute 5` and discharges it on further rotation througlitlie chutel.

Thus tlf` buckets of the'drum receive, during retail? 11, alternately water, distilling gases, theTiinaterial intended for delivery, and air, and yit Willbe understood that no air can beflie yinto 'the furnace by the delivery device it, on the contrary, distilliiig gases from tl lfurnace' are taken out of the same. 1' l I prefer to provide rforvtlie adjustability of the rotatory speeil of the drum, to change thel saine Whenever conditions requires" Also the scrapertable may be so constructed .as to permit of a precise regulation and control of the quantity discharged in order that the' device may be so adjusted that the buckets are only partly filled with vmaterial and :jammings and, injuries .to the material dur- -ing -the discharge vor delivery are, thereby avoided. i
